[0011]
In addition, the transmitting and receiving devices can be provided as a transmitter / receiver, if necessary, integrally.
Thus, when the vehicle 10 on which the anti-theft device 1 is mounted is stolen, the specific device detected by the anti-theft device 1 from the mobile phone 11 or any of the transmitters 12, 13, and 14 is detected. When a radio wave including an ID number is transmitted, the radio wave is received by the receiving unit 3 of the anti-theft device 1, the detection unit 4 detects the specific ID number, and the transmission unit 5 transmits a radio wave of a specific frequency. send.
[0012]
Then, the radio wave of the specific frequency is directly received by the receiver 21 installed in the police car or the receiver 22 installed in the road facility, so that the presence of the stolen car 10 and the presence of the car 10 Location information can be obtained. Alternatively, the presence of the stolen vehicle 10 is received by one of the mobile phone 19, the receiver 20 installed at the police station, and the other receiver 23 via one of the relay means 24, 25, and 26. And the location near the stolen vehicle 10 can be known from the location information such as the installation location of the relay means 24, 25, and 26, whereby the vehicle 10 transported to a remote location can also be known. It can be easily found. Further, since the system using the anti-theft device 1 can use a mobile phone, transmission / reception becomes extremely easy, and a stolen vehicle can be found only by the victim.
